Development-Setup

This ansible role is developed using molecule for testing. It's development is based on visual studio code and a regarding development container, solving all dependencies in terms of necessary tools (ansible, linter, molecule).

The role will be tested on two ubuntu containers (focal, jammy).

To startup the molecule test containers from within the development container, the docker socket needs to be bind mounted into the development container.

Important folders and files

.devcontainer

Defines the Dockerfile for the development container
Configures the development container startup (e.g. bind mount docker socket)

molecule/default/Dockerfile.js

Used as a template for all platforms defined in molecule/default/molecule.yml
Prepares the environments to support systemd services (necessary for some ansible roles acting on systemd)
Installs all requirements to run ansible against the derived container
The file is aligned with the attributes of the platforms in molecule/default/molecule.yml
For more information - study the molecule documentation

Usage

Visual Studio Code
